Bike— Part 1 채점 보고서

제안: 句子內容完整但過於冗長，應該更自然地分成兩到三句以提高清晰度與流暢度；使用更多具體細節（例如年齡、騎車的地點或特別的回憶）會讓回答更豐富且有說服力；注意避免語法小錯誤與重複表達，如“used to”與時態一致。

예시: Yes, I had a red bike when I was about eight. It was a birthday present from my parents, and I loved it because I often rode it with my cousins around the neighborhood. Riding it made me feel independent and confident.

제안: 回答有想法但表達不夠準確且有語法與詞彙錯誤（例如“on our sale”顯然用詞不當）；應先直接回答問題，再用一到兩句具體細節或例子說明共享單車的使用方式與流行原因；使用合適的連接詞使敘述更連貫。

예시: Yes, bikes are very popular, especially shared bikes in cities. People can unlock them by scanning a QR code with their phones, use them for short trips, and then leave them at another designated spot when they finish.

× Yes, I had a red bike when I was a child and it was a birthday gift from my parents and I liked it very much because I used to ride it with my cousins and it made me feel independent.

✓ Yes, I had a red bike when I was a child. It was a birthday gift from my parents, and I liked it very much because I used to ride it with my cousins; it made me feel independent.

句子本身时态使用基本正确（过去时），但原句过长且缺少适当标点，导致可读性差。将句子拆分并加上逗号或分号有助于清晰表达不同的动作和原因。建议在英语写作或口语中使用适当的断句，使听者或读者更容易理解。

× Yeah, I think bikes are quite popular in my country, but we call this shared bikes and we can scan the QR code. That means you borrow it for a while and then we can return it on our sale on our phones when we don't need it.

✓ Yeah, I think bikes are quite popular in my country, but we call these shared bikes and we can scan a QR code. That means you borrow one for a while and then you can return it on your app on your phone when you don't need it.

原句存在多处现在时和名词搭配的问题：1) 'this shared bikes' 主谓不一致且指示词与名词数不匹配，应为 'these shared bikes'（指复数）或 'this shared bike'（指单数）。2) 'scan the QR code' 更自然为 'scan a QR code'，因为每辆车通常有各自二维码。3) 'you borrow it for a while and then we can return it' 人称不一致，需统一为 'you ... you ...' 或 'we ... we ...'，此处根据说明把动作主体改为泛指 'you'。4) 'on our sale on our phones' 可能为口误，应为 'on your app on your phone'（在手机应用上）。以上修改统一现在时表达并修正代词与名词搭配。建议注意指示代词与名词单复数一致、代词人称一致以及使用恰当名词（app vs sale）。
